Description
La présente invention a pour objet des perfectionnements aux machines de chauffage d'articles ou produits par condensation de vapeurs sur ceux- ci.The present invention relates to improvements in machines for heating articles or products by condensation of vapors thereon.
On connaît des machines de chauffage d'articles ou produits par condensation de vapeurs sur ceux- ci (voir, par exemple, FR-Al -2.243.045, FR-A1-2.553.186 et US-A-4.055.217). Dans ces machines, les articles ou produits sont chauffés à la température désirée par condensation de vapeur primaire. Comme le liquide primaire constituant la source de la vapeur primaire est habituellement un liquide perfluorocarbure inerte à haut point d'ébut- lition très coûteux, il est usuel de confiner la masse de vapeur primaire vis-à-vis de l'atmosphère par une masse de vapeur secondaire générée à partir d'un liquide secondaire habituellement un chloro- fluorocarbure, d'un point d'ébullition moins élevé que le liquide primaire. Il est connu aussi de prévoir des moyens de condensation de la vapeur secondaire pour éviter que celle-ci ne s'échappe à l'atmosphère et de recycler le condensat de vapeur primaire dans la machine. Il est connu, également, de séparer le liquide secondaire de l'eau provenant de l'atmosphère contenue dans le condensat par élimination de l'eau surnageante dans un séparateur (voir, par exemple, US-A-3.632.480 et EP-A1-0112.484).Machines for heating articles or products by condensation of vapors on them are known (see, for example, FR-A1-2,243,045, FR-A1-2,553,186 and US-A-4,055,217). In these machines, the articles or products are heated to the desired temperature by condensation of primary steam. As the primary liquid constituting the source of the primary vapor is usually an inert perfluorocarbon liquid with a high boiling point which is very expensive, it is customary to confine the mass of primary vapor with respect to the atmosphere by a mass secondary vapor generated from a secondary liquid, usually a chlorofluorocarbon, with a lower boiling point than the primary liquid. It is also known to provide means for condensing the secondary steam to prevent it from escaping to the atmosphere and to recycle the primary steam condensate in the machine. It is also known to separate the secondary liquid from the water coming from the atmosphere contained in the condensate by elimination of the supernatant water in a separator (see, for example, US-A-3,632,480 and EP- A1-0112.484).
L'invention a pour objet de fournir divers perfectionnements au type de machines susindiqué.The object of the invention is to provide various improvements to the type of machines mentioned above.
Un premier perfectionnement a pour but d'abaisser la teneur en ions chlore et fluor dans les vapeurs primaire et secondaire de l'équipement et provenant de la décomposition de ces vapeurs. Dans ce but l'invention prévoit un lavage amélioré du liquide secondaire. De plus, un balayage de gaz secs interposé entre l'air atmosphérique humide et la vapeur secondaire s'oppose à l'introduction de l'humidité atmosphérique.A first improvement aims to lower the content of chlorine and fluorine ions in the primary and secondary vapors of the equipment and resulting from the decomposition of these vapors. For this purpose, the invention provides for improved washing of the secondary liquid. In addition, a sweep of dry gases interposed between the humid atmospheric air and the secondary vapor is opposed to the introduction of atmospheric humidity.
Un autre perfectionnement consiste à compenser automatiquement les variations du régime de fonctionnement par un contrôle du bilan de puissance.Another improvement consists in automatically compensating for variations in the operating regime by controlling the power balance.
Ces perfectionnements seront décrits ci-après d'une façon plus détaillée en regard du dessin annexé donné à titre d'exemple, sur lequel la figure 1 est une représentation schématique d'une machine perfectionnée, tandis que la figure 2 est une coupe détaillée du laveur d'acide montré à la droite de la figure 1.These improvements will be described below in more detail with reference to the attached drawing given by way of example, in which FIG. 1 is a schematic representation of an improved machine, while FIG. 2 is a detailed section of the acid washer shown to the right of Figure 1.
On a représenté schématiquement sur la figure 1 un exemple de machine auquel les perfectionnements de l'invention peuvent s'appliquer.There is shown schematically in Figure 1 an example of machine to which the improvements of the invention can be applied.
Cette machine comprend une cuve verticale 1, par exemple de section rectangulaire, comprenant, du bas vers le haut, du liquide primaire 2 (habituellement du perfluorocarbure liquide) pouvant être porté à l'ébullition par un ou plusieurs éléments chauffants 3 et/ou des moyens équivalents (bain- marie), une chambre de chauffage 4 de l'article ou produit à chauffer remplie, en service, de vapeurs du liquide primaire; un serpentin thermostaté 5 de condensation des vapeurs de liquide primaire maintenu à une température intermédiaire entre les points d'ébullition des liquides primaire et secondaire; une zone 6 remplie d'une masse de vapeurs d'un liquide secondaire (habituellement un chlo- rofluorocarbure) ayant un point d'ébullition inférieur à celui du liquide primaire, cette masse de vapeurs formant bouchon pour les vapeurs de liquide primaire; un serpentin refroidi 7 de condensation des vapeurs de liquide secondaire. La vapeur secondaire peut être générée par injection de liquide secondaire par le moyen d'une rampe pul- vérisatrice 8, comme représenté, reliée à un réservoir de liquide secondaire. En variante, le liquide secondaire pourrait être simplement mélangé avec le liquide primaire 2.This machine comprises a
Le liquide secondaire condensé sur les serpentins 7 est recueilli dans une gouttière 9 et dirigé vers le dispositif épurateur de la figure 2 qui constitue l'un des perfectionnements de l'invention. Après épuration, le liquide secondaire sert à alimenter la rampe 8 (ou est renvoyé dans le bas de la cuve dans le cas de la variante signalée).The secondary liquid condensed on the
On décrira maintenant plus en détail les divers perfectionnements fournis par la présente invention.The various improvements provided by the present invention will now be described in more detail.
En raison d'un processus de dégradation thermique, des ions H+, CI-, F- apparaissent dans la vapeur secondaire au contact avec l'humidité atmosphérique. Ces ions donnent naissance à des acides qui provoquent: la corrosion de l'équipement et la pollution des articles et pièces chauffées.Due to a thermal degradation process, ions H + , CI-, F- appear in the secondary vapor on contact with atmospheric humidity. These ions give rise to acids which cause: corrosion of equipment and pollution of heated articles and parts.
If faut donc éliminer ces ions et éviter de les recycler dans la machine; il faut également éviter l'introduction d'humidité dans celui-ci.It is therefore necessary to eliminate these ions and avoid recycling them in the machine; it is also necessary to avoid the introduction of moisture into it.
Le dispositif laveur d'acide représenté en détail sur la figure 2 comporte un premier bac 80 placé sur le retour 80a des condensats qui traverse une couche d'eau 81 afin de piéger les ions. Pour favoriser le lavage, un diffuseur 82 divise les condensats en fines gouttelettes avant pénétration dans l'eau. La couche d'eau est alimentée à niveau constant par une injection d'eau propre avec diffuseur 84, en point bas du laveur et sortie d'eau polluée en haut au niveau n3. Un col de cygne 85 sur la canalisation 86 d'amenée de l'eau de lavage évite un retour de liquide secondaire dans l'eau, qui pourrait bloquer le débitmètre 87. Au niveau n1, le liquide secondaire, éventuellement chargé légèrement en eau, est prélevé à travers une électrovanne 88b. Cette électrovanne permet d'isoler le bac 80 des bacs 88 et 89 pendant les périodes d'arrêt et de démarrage de l'équipement. Le bac 88 permet d'assurer le remplissage en début ou en cours d'opération de l'équipement. I est muni d'un couvercle amovible 88a pour le remplissage. Le bac 89 joue le rôle de réserve de liquide secondaire et de séchage de celui-ci sur un tamis moléculaire 90, afin d'éliminer toute trace d'eau. Cette disposition permet d'éliminer l'eau de lavage résiduelle ainsi que l'eau introduite en cours de chargement de l'équipement en liquide secondaire. Ce tamisThe acid washing device shown in detail in FIG. 2 comprises a
peut être constitué par exemple par de la zéolite formant un réseau cristallin de silico-aluminate dans lequel des cations monovalents K ou Na ou divalents ont été introduits, la taille des cations détermine la dimension des pores qui piègent l'eau. Une matière de ce genre est connue sous la marque «silliporite».can be constituted for example by zeolite forming a crystalline network of silico-aluminate in which monovalent K or Na or divalent cations have been introduced, the size of the cations determines the size of the pores which trap water. A material of this kind is known under the brand "silliporite".
Deux contrôles de niveaux S1 en 91 et S2 en 92 permettent de détecter le niveau minimum de marche, nécessitant un remplissage de l'équipement, et le niveau maximum de fin de remplissage.Two level controls S1 at 91 and S2 at 92 make it possible to detect the minimum level of operation, requiring filling of the equipment, and the maximum level at the end of filling.
Le choix des diamètres d et D des tuyauteries, le volume relatif du bac 88 par rapport aux bacs 80 et 89, et l'électrovanne 88b permettent d'éviter une arrivée d'eau directe dans le liquide secondaire de la réserve et des variations du niveau n2 intempestives, entraînant un écoulement du liquide secondaire par le rejet 93 déversant l'eau polluée.The choice of the diameters d and D of the pipes, the relative volume of the
La pompe doseuse 94 permet de recycler le liquide secondaire vers la cuve de l'équipement à travers les gicleurs de pulvérisation 23.The
Le niveau n2 détermine un volume V1 dans le bac 80. Le niveau n2 détermine dans le bac 88 un volume V 2 tel que V < V2. Le niveau n3 est déterminé en fonction de la différence des densités de l'eau de lavage (d = 1 ) et du liquide secondaire, dont la densité est voisine de 1,5. Le niveau n4 est variable durant la marche.The level n2 determines a volume V 1 in the
Pour éviter l'introduction d'humidité dans la machine on fait selon l'invention un balayage de gaz secs sur la partie supérieure de la cuve de la machine, ce qui empêche le contact direct de l'air atmosphérique avec les vapeurs produites dans la cuve. On voit sur la figure 1 des tuyères 95 réparties sur le haut de la cuve et par lesquelles de l'air sec est injecté radialement.To avoid the introduction of moisture into the machine, a dry gas sweep is made according to the invention on the upper part of the machine tank, which prevents direct contact of atmospheric air with the vapors produced in the tank. We see in Figure 1
Cette disposition permet, dans le cas de la polymérisation de polymères en phase vapeur, d'éviter l'introduction d'eau dans la vapeur primaire, si l'on minimise l'importance de la vapeur secondaire et, dans le cas du brasage, d'éviter l'introduction d'eau dans la vapeur secondaire.This arrangement makes it possible, in the case of polymerization of polymers in the vapor phase, to avoid the introduction of water into the primary vapor, if the importance of the secondary vapor is minimized and, in the case of brazing, avoid the introduction of water into the secondary steam.
Le bilan thermique de la machine est tel que l'énergie transmise par l'élément ou les éléments chauffants au liquide primaire, par le jeu de la vapeur primaire, équilibre la déperdition thermique des parois de la cuve, provoque l'évaporation du liquide secondaire, échauffe l'eau du serpentin secondaire et échauffe également la charge.The machine's thermal balance is such that the energy transmitted by the heating element or elements to the primary liquid, by the play of primary steam, balances the thermal loss of the walls of the tank, causes the evaporation of the secondary liquid , heats the secondary coil water and also heats the load.
En régime stabilisé, la déperdition des parois et l'énergie absorbée par la condensation du liquide secondaire sont des constantes, caractéristiques du dimensionnement de l'équipement. L'échauffement de l'eau sera donc la résultante de l'apport énergétique par les éléments chauffants et de l'absorption de la masse introduite.In stabilized conditions, the loss of the walls and the energy absorbed by the condensation of the secondary liquid are constants, characteristic of the dimensioning of the equipment. The heating of the water will therefore be the result of the energy supply by the heating elements and the absorption of the mass introduced.
Selon l'invention on régule donc le fonctionnement thermique de la machine en ajustant la puissance transmise aux éléments chauffants en fonction de la nature de la charge introduite, par contrôle de l'élévation de température de l'eau du serpentin 7, servant à condenser les vapeurs du liquide secondaire.According to the invention, therefore, the thermal operation of the machine is regulated by adjusting the power transmitted to the heating elements as a function of the nature of the charge introduced, by controlling the rise in temperature of the water in the
L'expérimentation montre que le temps de réaction de cette régulation est très court au regard de l'énergie thermique de l'équipement, permettant un maintien de la densité de vapeur environnant la pièce par la détermination d'une légère surchauffe résiduelle de l'eau du serpentin secondaire.Experimentation shows that the reaction time for this regulation is very short with regard to the thermal energy of the equipment, allowing the vapor density surrounding the room to be maintained by determining a slight residual overheating of the secondary coil water.
Des dispositifs annexes de contrôle des températures complètent l'équipement sur le plan de la sécurité.Additional temperature control devices complete the equipment in terms of safety.
